This invention relates to wind-shield cleaners especially adapted for cleaning automobile wind-shields and more partlcularshown in section and a portion of the casing being shown in section in order to illustrate the oil conduit for the flow of oil which 1s used in thiscase as a packing or seal.

This motor is especially designed to be used in connection with and to be operated through the suction of the engine manifold, but as will be hereinafter explained this motorcan be adapted for operation with other source of power such as air pressure or a 7 like medium.

In the drawin s. Fi ure I re resents a semi-cylindrical casing of suitable depth and having a head or cover secured hermetically thereto ,f this may be accomplished in any suitable manner preferably in the manner illustrated which is apparent without further "description,

Mounted 1n the casing l, is an oscillating flap-piston having a spindle 7 connected one or the other through the thereto'and moving with it and upon which the piston oscillates. The spindle 7 is mounted in bearings a and I) in the upper end in the casing 1 and the head 2.

Preferably formed integral with the head 2 is a v-alvecasing 3 in which the port controlling valve (5 operates. The valve casing 3 is provided with openings 9. 10 and 11 adapted to register with the ports 12. 13 and 1-1 of the port controlling valve 6. Vhen said valve is properly positioned through the operation of the piston spindle 7 this is accomplished by means of the projections 15 and 16 on the end of the spindle 7 which in turn engage a spring 17 secured at both ends or otherwise in the center of the valve 6; the projections 15 and 16 engaging the spring 17 just previous totlie full throw of the piston 8 in either direction. The function of the spring 17 is to provide means through the projections 15 and 16 for overcoming a spring pressedstopping or locating device, in this case comprising a ball 18 compressed by spring 19 with means for taking up or increasing the tension of the spring 19, such as a screw 20. The ball 18 is adapted to seat itself respectively in recesses such. as 21 formed in the periphery of the valve 6 as shown in Figures II and III. This serves to properly. locate the valve as it is oscillated in one or the other direction, so that the proper ports register. Openings 10 and 11 lead into ports 23 and 22 in the head 2 which in turn communicate with the upper portion of the casing and as suction is imparted to medium of the valve 6, the piston 8 is moved in that direction, the outer air in turn being allowed to enter the casing either through openings 13 or 14 in valve 6 through the opposite port 23 or 22 (see Fig. III).

It will be seen that the tension of the spring 17 will be increased gradually as the spindle moves to the completion of the stroke of, the piston, the resistance offered by the ball 18 in its seat 21tl1e tension of the spring 17 is released and the valve oscillated so as to properly bring the ports of valve and easing into communication.

The upper end of 'the valve casing 3 communieates with passage 4 which is controlled by a valve 5. This passage 4 in turn forms a means for connecting the motor through a flexible pipe with the manifold of the engine, suction being controlled through the valve 5.

where upon having overcome In order to provide for the packing or sealing of the piston 8, oil orifices 24 and 25, which communicate, are provided. Thus as the piston 8 moves to the center from either direction, a predetermined amount of oil is provided. Any suitable oil cup may be used for this purpose, and mounted at the upper end 24 of the casing.

The end 26 of'the spindle 7 is provided with suitable means for attaching a cleaner sweep or cleaner proper which may be of any suitable construction.

This invention is not limited to the details of construction illustrated and described, inasmuch as they may be varied without departing from the invention.

Claims: 1

1. A motor of the type set forth comprising a casing, a spindle and a piston mounted thereon adapted to operate within said casing, a port controlling valve mounted exterior of said casing and in line with the piston spindle, detaining means adapted to hold said v ve immovable during a portion of the oscillation of said s indle, aspring connection between the spindle and the valve operated directlyby the spindle and brought under tension'by the action of said spindle said detaining means.

2. A motor of the type set forth comprising a casing, a spindle and a piston mounted thereon adapted to oscillate within said casrlor of said casing and in line with the piston spindle, means for holding said valve immovable during a portion of the piston movement, a spring connection between the spindle and the valve operated directly by the spindle and brought under tension by the action of said spindle; the tension thus created in said spring being adapted to overcome the resistance offered by the means for holding said valve immovable and to rapidly oscillate the valve at approximately the end of the piston stroke.
